The JVC Kenwood GY-LSX2 and JVC Kenwood GW-SPLS1 4K Micro Four Thirds camera prototypes have been revealed at NAB Show 2014 along with their preliminary specs lists.

The company has also confirmed that a couple of prototypes will be displayed during the event. Well, the promise has been delivered as both the GY-LSX2 and GW-SPLS1 camcorders have been revealed at the Las Vegas-based show.

JVC GY-LSX2 4K Micro Four Thirds camera revealed at NAB Show 2014 as a prototype

JVC Kenwood GY-LSX2 will be able to record and stream 4K videos at the same time.

JVC Kenwood has first showed the GY-LSX2 which features a Super 35mm image sensor capable of shooting videos at 4K resolution. The sensor measures 22.6 x 17mm, meaning that it is bigger than regular Micro Four Thirds sensors – around the same size as the APS-C sensors.

The device is running on a 13.6-megapixel Altasens AL41410C SoC (system-on-a-chip) sensor + processor which can handle frame rates of up to 72fps. However, the JVC GY-LSX2’s frame rate will be limited to 30fps.

This handheld camcorder will be able to record 4K footage directly on the SD card, just like the Panasonic GH4, but unlike the Sony A7S which can only do so on an external recorder.

Another big plus for this camera is the ability to stream and record videos at the same time. There are no availability details, but rumors are claiming that it will come by the end of 2014 for around $15,000.

JVC GW-SPLS1 is the second 4K Micro Four Thirds camera prototype to be shown at the event

JVC Kenwood GW-SPLS1 features a 7-inch screen. It is still in prototype stage, but it will record 4K videos when it becomes available on the market.

The second model is the JVC GW-SPLS1 and it consists of two separate bodies: the camera and the video unit. This system features the same Altasens SoC with a 13.6-megapixel Super 35mm sensor, albeit it provides a higher frame rate standing at 60fps.

It can record 4K videos on a SDHC/SDXC card and features a foldable 7-inch screen on the movie unit. Users will also receive a 5-meter cable in the package, although they will be able to buy cables of up to 20 meters in length.

The company has not revealed many details, like in the case of its sibling, therefore Micro Four Thirds will have to remain a little patient.

The good thing is that the Micro Four Thirds family is growing at a fast rate. From Panasonic and Olympus at the beginning, now it includes Zeiss, Kenko (Tokina), Tamron, JK Imaging (Kodak), Blackmagic Design, and Schneider-Kreuznach among many others.
